Description

Technical Field

[0001] The invention relates to a shielding cover. Background Art

[0002] Electronic devices (such as laptops) are small in size and their internal space is bound to be relatively cramped. Therefore, multiple solder wires or board-to-board (BTB) electrical connectors are usually used to electrically connect the circuit boards to each other to achieve better space utilization.

[0003] Metal shielding covers are generally metal parts added to the outside of ICs or electronic components that require EMI (Electromagnetic Interference) shielding to prevent external noise interference and avoid electromagnetic interference generated by themselves from affecting other signals.

[0004] Generally, two separate metal parts, shielding cover and shielding frame, or one shielding cover is used to save costs. The above method is not easy to disassemble and it takes more time to fasten. The shielding cover is often deformed after removal and cannot be used again. An additional shielding cover is required, resulting in higher maintenance costs. Another method is to use shielding clips instead of shielding frames, but there are still some problems to be solved, such as the clamping force, the size of the gap, the height of the shielding cover, etc. Summary of the invention

Figure 2A For decomposition diagram, Figure 3 This is a schematic diagram of the back appearance. Figure 4 This is a side cross-sectional schematic diagram before the cover is closed. Figure 5 In this embodiment, the shielding case includes a frame body 1 and an outer cover 2.

[0062] In this embodiment, both sides of one end of the frame body 1 include a first shaft portion 11, and the frame body 1 includes a first fixing portion 12. The outer cover 2 covers the frame body 1, and both sides of one end of the outer cover 2 include a second shaft portion 21 pivotally connected to the first shaft portion 11, and the outer cover 2 includes a second fixing portion 22 corresponding to the first fixing portion 12, and an opening 13 is formed between the other end of the frame body 1 and the corresponding outer cover 2.

[0063] In this embodiment, the frame 1 and the outer cover 2 are combined into a metal shielding cover. When the SMT process is performed, there is no need to attach an additional plastic sheet for the vacuum nozzle of the SMT machine to pick up. In addition, after the outer cover 2 is combined with the frame 1, there is still a partial gap (opening 13) to facilitate the entry of hot air in the SMT process, ensuring good soldering of the circuit board and electronic components of the board to board (BTB).

[0064] In this embodiment, in more detail, the shielding cover can cover the circuit board 3, and a socket-type board-to-board (BTB) electrical connector is provided on the circuit board 3, which can provide another plug-type board-to-board (BTB) electrical connector for docking. This plug-type board-to-board (BTB) electrical connector is combined with another circuit board 3, and the wire 4 (such as Fig.17 As shown in FIG. 1 , the wire 4 is pulled out of the opening 13. In other words, the opening 13 is filled and shielded by the wire 4. The above is not limited to this. In some embodiments, in addition to being used in BTB electrical connectors, it can also be used on other electronic components or connectors that require EMI shielding.

[0065] In this embodiment, in more detail, the frame 1 is a square frame structure, and the two sides of the frame 1 respectively include a plurality of first side panels 1a, and the other end of the frame 1 includes a first bottom plate 1b. Here, the plurality of first side panels 1a and the first bottom plate 1b are designed to be vertical. In addition, the outer cover 2 is a square flat plate structure, and the two sides of the outer cover 2 respectively include a plurality of second side panels 2a covering the outside of each first side panel 1a, providing a double-layer metal shielding effect. In addition, the other end of the outer cover 2 includes a second plate 2b corresponding to the first bottom plate 1b.

[0066] In this embodiment, in more detail, each first shaft portion 11 has a rotating shaft 111 protruding from the side end of each first side plate 1a, and each second shaft portion 21 has a shaft hole 211 formed at the side end of each second side plate 2a, and the rotating shaft 111 is inserted into the shaft hole 211. It is particularly noted that the shaft hole 211 is an elongated slot hole, providing the rotating shaft 111 with displacement in the elongated slot hole. In addition, the rotating shaft 111 and the shaft hole 211 can be further interchanged. For details, please refer to Figure 2B As shown, each first shaft portion 11 has a shaft hole 112 protruding from a side end of each first side plate 1 a , and each second shaft portion 21 has a rotating shaft 212 formed at a side end of each second side plate 2 a , and the rotating shaft 212 is inserted into the shaft hole 112 .

[0067] In this embodiment, in more detail, the first fixing portion 12 forms a slot 121 at the side end of each first side plate 1a, and the two sides of the second plate 2b are locked in each slot 121. When the outer cover 2 is closed on the frame 1, the two sides of the second plate 2b are located outside each slot 121, and the outer cover 2 is slid to the top of the frame 1, and the two sides of the second plate 2b are locked in each slot 121. In addition, when the outer cover 2 is to be opened, the design of the second plate 2b extending outward from the other end of the outer cover 2 provides the benefit of moving with hands or tools, so that the two sides of the second plate 2b are separated from the slots 121, and then the outer cover 2 is opened. In other words, the protruding design of the front edge of the second plate 2b and the design of the side of the second plate 2b protruding from the slot 121 make it convenient for operators to open the outer cover.

[0068] Reference Figure 1B Furthermore, the second plate 2b extends toward the first bottom plate 1b and covers the opening 13, providing a shielding effect on the opening 13, thereby improving the EMI (Electromagnetic Interference) / RFI (Radio Frequency Interference) problem during high-speed signal transmission.
